Ive used this period to go on walks off the beaten track and avoiding the usual parks and trails. Even walking to other areas of Merthyr just on the streets. Taken a couple of nostalgic walks to the estates I grew up on as a kid.
Like you say, people are not being very observant of the rules, usually if I am on a path or pavement and someone is coming in the opposite direction its usually me who moves out of the way first and is more conscious of social distancing.
